Low pressure drop with high flow rates.

Air operated PTFE diaphragm design; no wetted metals or elastomers.

Suitable for pressure service through 100 PSI, no differential required.

Normally-closed design provides bubble-tight shut off in the event of air or electrical failure.

Patented Fail-Dry® safety design warns of seal failure; permits valve to continue operating.

Can be mounted in any position.

Placed at the high point of a piping system, this patented valve will vent gas as it occurs.

A unique float/actuating lever allows the vent orifice to open when gas is present.

After gas vents, rising liquid forces the vent to close.

Whenever gas accumulates, the valve will re-open until the gas is vented.

Designed for systems that continuously generate trace amounts of gasses.

When three types of venting valves are needed, this valve will serve the function of all three.

Functions as Air Release Valve, which releases air during system start up.

Functions as Degassing Valve, which provides continuous degassing.

Functions as Vacuum Relief Valve, which prevents pipeline vacuum in case of leaks or siphon.

Self-guided, high buoyancy float, in combination with the elastomeric sealed poppet assures leak tight sealing with minimal emission of process fluid.

Angle pattern valve with high pressure and flow rates.

Relief setting is infinitely adjustable from 5 psi to 150 psi with 210 psi max inlet.

Single flat diaphragm ideal for salt crystallization problems that often cause valve sticking.

Patented Fail-Dry® advance warning vent allows maintenance to be scheduled conveniently, without costly shut-down.

Relief setting is infinitely adjustable from 5 psi to 125 psi - 5-100 psi on 3" and 4" sizes.

Functions as relief, bypass, back pressure, anti-siphon valve and back pressure regulator.

Unique internal flow path provides highest flow rates at set pressure.

Rolling diaphragm provides high accuracy, prevents crystallization.

Flat secondary diaphragm provides a second isolation of the control spring.

Patented Fail-Dry® safety vent gives advance warning of need to replace primary seal.

Relief setting is infinitely adjustable from 5 psi to 100 psi.

Not recommended for applications with vacuum or back pressure on the outlet.

Flexible elastomer disc offers very low pressure sealing.

Requires extremely minimal pressure to move to the open position.

Self-centering disc seals in same position every time, allowing more reliable sealing and prolonged life.

R disc is kept clean by the constant flushing action of the inlet flow, keeping the sealing area free of particles.

Should be installed so gravity will allow the disc to rest against the valve seat when flow is not present.

Leak-free sealing protects against the potential hazards created by reverse flow of corrosive liquids.

Not dependent upon gravity - mount in any position.

Maintain constant flow with inlet pressure fluctuation from 15 to 120 PSI (1 Bar to 8 Bars) with ±15% accuracy. Test equipment is NIST certified.

For corrosive and Ultrapure liquid applications.

Standard flow ranges from 1/4 GPM to 8 GPM; 9 to 120 GPM by special order.

No metals in contact with the liquid.

Automatic in operation - no adjustments.

Converts varying inlet pressure to a stabilized, lower pre-set downstream pressure.

Large surface area of its frictionless rolling diaphragm provides exceptional sensitivity.

Free movement of the diaphragm on a balanced shaft assures smooth, accurate performance and reliable sealing for millions of cycles.

Double U-cups prevent leakage along the shaft and eliminates the possibility of "creep".

Designed for higher flow capacities and less system pressure loss.

For applications requiring a compact, cost-effective and high-pressure rated valve with extended cycle life.

Only 4-9/16'' high, these valves are ideal for limited space installations.

Low unit cost coupled with high pressure ratings and considerable flow rates (Cv of 0.5 or 0.8) offer excellent opportunities for systems requiring quick opening/quick closing solenoid valves.

Particularly for applications where high back pressures (up to 70 PSI) are required e.g. controlling flow to spray nozzles, high pressure chemical injections, etc. Inlet pressure to 140 PSI.

PTFE Bellows barrier type dynamic seal prevents leaking of fugitive emissions to the atmosphere.

Normally closed, Inline design with bubble-tight shut-off.

Pilot requires minimum 5 PSI differential to operate.

Particularly for applications where high back pressures (up to 70 PSI) are required e.g. controlling flow spray nozzles, high pressure chemical injections, etc. Inlet pressure to 140 PSI.

Allows safe expulsion of unwanted air in piping system.

Unique self-guided poppet assures minimal emission of system liquid prior to sealing.

Poppet seals more reliably than ball design; does not deform under pressure like a hollow ball.

Closes at 0 PSI, as long as liquid is present. Valve closes as liquid rises, after virtually all unwanted air is forced out.

Seals bubble-tight at system pressures as low as 10 psi (EPDM seals).
